Magnetization of La(2-x)Sr(x)NiO(4+ delta) (0 < x < 0.5) and observation of novel memory effects
P. G. Freeman, A. T. Boothroyd, D. Prabhakaran +1
We have studied the magnetization of a series of spin-charge ordered La(2-x)Sr(x)NiO(4+delta) single crystals with 0 < x < 0.5. For fields applied parallel to the ab plane there is…
Three-Dimensional Spin Fluctuations in Na0.75CoO2
L. M. Helme, A. T. Boothroyd, R. Coldea +4
We report polarized- and unpolarized-neutron scattering measurements of magnetic excitations in single-crystal Na0.75CoO2. The data confirm ferromagnetic correlations within the co…
Magnetic Studies of Polycrystalline and Single-Crystal NaxCoO2
D. Prabhakaran, A. T. Boothroyd, R. Coldea +2
We have investigated the preparation and bulk magnetic properties of NaxCoO2 in the range 0.5<x<0.95, including those for single crystals grown by the floating-zone method in an im…
Magnetic excitations in LaSrCoO
L. M. Helme, A. T. Boothroyd, D. Prabhakaran +3
We report magnetization and neutron scattering measurements of the half-doped compound LaSrCoO, which exhibits a checkerboard pattern of charge ordering below ~…
Observation of 3D Heisenberg-like ferromagnetism in single crystal La_{0.875}Sr_{0.125}MnO_3
Sunil Nair, A. Banerjee, A. V. Narlikar +2
We report measurements and analysis of the magnetic critical phenomena in a single crystal of LaSrMnO. The critical exponents associated with the ferr…
